pH indicator papers, Duotest and Tritest

: MACHEREY-NAGEL

By the combination of several indicators on one test paper, a better recognition between different pH values is achieved. This makes the correct pH reading easier.

Long term stable and protected against external influences due to plastic reel
No accessories needed, always ready to use
Reliable results due to easy and accurate read-off from colour scale
Several indicators for more precise readings

Duotest indicator papers combine two different indicator zones on a single strip. The zones are separated by a hydrophobic barrier, which effectively prevents mixing of the reaction colours and increases the mechanical stability.

Tritest indicator paper has three different indicator zones on a single paper. The three zones guarantee optimal colour differences and safe determination of in-between values. Tritest indicator paper is available for a pH range from 1 to 11 and feature 1 pH unit increments.

In Tritest L indicator paper, two hydrophobic barriers separate the indicator zones. Even in strongly alkaline solutions, the colours of the zones do not mix.
